The industry has also been pursuing X-ray light sources as a path to the future.
But new X-ray sources known as synchrotrons have reduced data collection time to a few days or even less than a day.
The system is an X-ray source and the primary star appears to be suffering from substantial mass loss.
Very few X-ray sources ever exceed one crab in brightness.
But there are certain X-ray sources consisting of binary stars.
The mean density of X-ray sources is about one source per square degree.
These two ideas account for several types of known X-ray sources.
Far behind, hard X-ray sources were faded to pale red stars.
Finally, some of these galactic X-ray sources were found to be highly variable.
These early X-ray sources still are studied and often produce significant results.
